Power source from fuse box?

I'm looking at post #13 that says the power went through the dark brown wire in the switch. I have a brown wire with white stripe that does connect to a terminal on the switch so I doubt its for the pump since its a 2 speed switch. I can't find any reference to a washer pump on the wiring diagrams.

What diagram are you looking at? I looked up the OEM factory manual, not the aftermarket one. The engine bay diagram shows the pump and connection (the one wire) to the bulkhead connector, and the instrument panel wiring shows the brown coming from the wiper switch to the bulkhead.

I don't remember. I think on some switches, you push in the whole knob, and on some there's a center button.
